It’s good to be king.

If you’re planning to go big or go home with your new mattress, you’ll want to make sure you’ve snagged the very best.

We’ve rounded up some of the best king-size mattress options available across different price points and sleep needs and have some savvy shopping some tips for you too.

You’ll find a few different types of king-size mattresses on the market as you peruse your options. These include:

  • memory foam
  • latex
  • innerspring
  • hybrid (a cross between innerspring and foam)

There are also several sizes of king-size mattresses.

  • regular king (typically 76 inches x 80 inches)
  • California king (typically 72 inches x 84 inches, which is great for sleepers over 6 feet tall)
  • split king (each side is adjustable to raise and lower)
  • Alaskan king (typically the largest mattress available, at approximately 108 inches x 108 inches)

Crowning the best kings took some legwork. Here’s how we did it:

  • We reviewed company policies. Specifically, we dove into warranties, in-home trials, shipping, and return policies.
  • We looked at company reputation and transparency. Each of the brands we feature has a positive reputation, transparent business practices, good customer reviews, and meets federal flammability requirements.
  • We prioritized. We chose mattresses with good materials certifications and included brands that sell a range of king sizes.

  • Height: 13 inches

Research suggests a medium-firm, self-inflated mattress (like this Saatva mattress) is best for back pain.

Pro: It’s puncture resistant, so it’s a great choice for those with pets and children.

Con: It’s only intended for indoor use, so don’t drag it outside. Also, this air mattress is a bit hefty at around 20 pounds, so it’s also not the most travel-friendly option.

Be sure to do your research and consider your needs, lifestyle, and sleep style (side, back, stomach, etc.) when shopping for your king-size mattress. Many mattresses will say what sleep position they’re intended for, but in general, opt for something firmer if you’re a back sleeper and softer if you’re a stomach or side sleeper.

Take a look at the mattress’s materials too. You may want to consider materials certifications like GOTS or GOLS. You might also want to think about whether you find foam comfy or if you’d prefer the extra support from springs.

It’s also best to try to test the mattress in person if you can. A test drive is often the fastest way to know if a specific mattress is the one for you! However, if you can’t try the mattress out ahead of time, buy from a company that offers an in-home trial period and a good return policy. Also, take a look at the warranty to see what’s covered.

There are many king-size mattress options, sizes, and price ranges available.

These 11 options checked our boxes for reputation and quality, but be sure to do your research before committing to a brand. Try to test the mattress out in person if possible, or buy from a company that offers an in-home trial.
